Stem Malay words

stem_malay() will find the root words in a dictionary, in which the malayrootwords data frame can be used, then it will remove “extra suffix”“,”prefix” and lastly “suffix”

To stem word “banyaknya”. It will return a data frame with the word “banyaknya” and the stemmed word “banyak”:

Note: ‘Root Word’ is now returned instead of ‘root_word’

stem_malay(word = "banyaknya", dictionary = malayrootwords)

'Root Word' is now returned instead of 'root_word'
   Col Word Root Word
1 banyaknya    banyak

To stem words in a data frame:

  1. Specify the data frame
  2. Specify the dictionary
  3. Specify the column that needs to be stemmed
x <- data.frame(text = c("banyaknya","sangat","terkedu", "pengetahuan"))

stem_malay(word = x, 
          dictionary = malayrootwords, 
          col_feature1 = "text")
  
'Root Word' is now returned instead of 'root_word'
     Col Word Root Word
1   banyaknya    banyak
2      sangat    sangat
3     terkedu      kedu
4 pengetahuan      tahu

Remove URLs

remove_url will remove all urls found in a string

x <- c("test https://t.co/fkQC2dXwnc", "another one https://www.google.com/ to try")
